Manjaro kde~

Starting EAF worked well, but after a while web pages would corrupt and become black. Following is the info from the eaf buffer. Python dependences are all installed by pip3.

Any clue is welcome! Thanks for you guys' work on this awesome project.

Can you test again after upgrade to newest version?

Better give me a step may be reproduced, thank you for your feedback! ;)

Still, the same error occurred. The crash timing depends... trying to figure out what triggers it.

It frequently crashes when bing or baidu is opened. I set the blank page to bing.

I tried, but it didn't work for me. I also tested GNU Emacs 27.0.50 (build 1, x86_64-pc-linux-gnu, GTK+ Version 3.24.13) of 2019-12-24, same issue.

Hi all.

I have push new commit e3414eb

Please update newest version first.

*eaf* buffer will print backtrace information when next time EAF core dump.

Then paste content of *eaf* here, thanks for feedback.

Looks code crash in Qt, and not Python side.

So far no further idea, thank you feedback.

I found EAF browser will crash if network disconnect, such as 4G network.

Still have no idea how to fix this problem, perhaps we need wrap gdb with Python to find backtrace when crash.

@manateelazycat

Hi all, please update to newest version first.

Please use the following way to collect crash information:

  1. Install gdb and turn on option eaf-enable-debug
  2. Use command eaf-stop-process stop current process
  3. Restart eaf, send issue with *eaf* buffer content when next crash

I believe this issue has fixed by 189dce5

Before above patch, QtWebEngineProcess won't quit even we close EAF Browser Buffer, with more pages viewed, the more QtWebEngineProcess background process until OUT OF MEMORY.
This patch delete QWebEnginePage object manual before close EAF Browser Buffer.

赞，我再考虑要不要直接从README中去掉pip3的安装方式，毕竟浏览器崩溃太影响使用了。

最好别，毕竟不是所有人都用arch
